Issue: Small UI issue with big penalties

I never understood logic, why default button is "choose image" in the window that showing after image selecting (Import frames from image strip) , instead of "add" image that we got to press after image was selected. You always got to move mouse on the big distance and no way to use keyboard "enter" as long as it will open explorer.So, please make "add" as default button in this window after we selected the image for frame, because we using it in 99% of cases
